If the screen interface is made smaller for miniaturized terminals, then the terminal size is reduced, but the operation convenience deteriorates

Engineering Contradiction:

Solution Approach 1:

The patent replaces the mechanical touch screen interface with an antenna-based electromagnetic signal detection system. The antenna detects signal changes caused by human body approach or contact, enabling control without requiring a physical interface. This substitution allows miniaturized terminals to maintain small size while improving operation convenience through gesture-based control.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces the antenna as an intermediary between the user and the terminal control system. Instead of direct touch on a small screen, the antenna mediates by detecting electromagnetic signal changes from human body proximity or contact, translating these physical interactions into control commands. This intermediary approach enables effective control in miniaturized devices where direct screen interaction becomes difficult.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 1:

The patent replaces the need for a large mechanical touch screen with an antenna-based detection system. By detecting electromagnetic signal changes from human body interaction, the system provides convenient operation controls without requiring a large display interface, thus maintaining small terminal size while improving ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent transitions from two-dimensional screen-based interaction to three-dimensional spatial detection. The antenna detects signal changes in three-dimensional space as the human body approaches or contacts different areas of the terminal, enabling comprehensive control functionality without increasing the terminal's physical footprint.

Solution Approach 1:

The patent introduces dynamic, multi-mode control through antenna detection. Instead of static touch points, the system detects varying electromagnetic signal patterns from different human body approaches, contacts, and movements. This dynamic detection enables diverse control modes (proximity control, contact control, gesture control) that maintain precision while adding operational interest and variety.

Inventive Principle:

Solution Approach 2:

The patent utilizes changes in electromagnetic signal parameters (signal strength, frequency, phase) caused by human body interaction to determine control commands. By monitoring multiple parameter variations rather than simple touch presence, the system achieves precise control recognition while enabling diverse interaction modes that enhance operational趣味性 through different detection scenarios.

Inventive Principle:

AI summary

Embodiments of the present disclosure disclose a terminal and a control method thereof. Cooperation between a target sensing object in the terminal and a target object to be sensed external to the terminal may affect a received signal on the target antenna loop, and control of the terminal may be implemented according to a change of the received signal. The method includes: detecting a received signal on a target antenna loop in the terminal and acquiring a signal parameter of the received signal; and determining whether the signal parameter of the received signal matches a preset target signal parameter, and triggering control of a to-be-controlled function of the terminal when the signal parameter of the received signal matches the preset target signal parameter.
